Specification of Letters Patent.

Application filed August 1, 1912. Serial No. 712,688.

Patented Mar. 31, 1914.

Gravity, in the county of Taylor and State of Iowa, have invented certain new and usedo hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to grain shockers and has for an object to provide a mechanism adapted to take sheaves of grain as dea -1 view of the improved shocker. -Fig. 2 is a -.v iew of the shocker in side elevation seen from the side employed adjacent the binder. Fig. 3 is a top plan view of the substructure or bottom with the superstructure removed.

livered from an ordinary self binder, turn the sheaves to standing position and assemble them in roper relation to be later delivered upon tl ie ground in such standing relation in the form of a shock.

A further object of the invention is to provide a mechanism adapted to be attached at the delivery endof the binder and to be the rear of such delivery end embodying a chute ositioned to receive a sheave from the dehvery end of the binder and to transfer it to the structure drawn in the rear of the binder and simultaneously to change the sheave from horizontal to vertical position, and with mechanism for delivering from the mechanism thesheaves so cone veyed.

A further object of the invention is to provide a structure embodying parallel adjacent compartments supported .upon hearing wheels with means for delivering sheaves alternately into the said compartopening said compartments and permitting the sheaves to drop upon the ground and to withdraw the mechanism from about and under such sheaves in such standing position.

A. further object of the invention is to provide adjacent compartments with supporting mechanism, each compartment being rovided with a bottom composed of paral-- lial adjacent 'strips'pivotally mounted with means for droppin such bottom and simultaneously turning t e strips on edge.

Apfurther object of the invention is to provide parallel adjacent compartments 'aving -a bottom and rearend adapted to be opened for deliveryt mechanism atthe forguide sheaves alternately into said compartments and a twisted conveyer chute terminating adjacent said guiding mechanism jWith these and other objects in view the invention comprises certain novel constructlons, combinations and arrangement of parts as will be hereinafter more fully de-, 7

scribed and claimed.

In the drawings :F igure 1 is a top plan Fig. 4 is a transverse sectional view through the shocker. Fig. '5 is a rear end elevation of the shocker. Fig. 6 is'a detail View show ing the operation of the bottom structure with the bottom raised in dposition to retain the sheaves' Fig. 7 is a tail view of the bottom structure shgwing" the bottom dropped in delivery position. Fig. 8 is a diagrammatic view showing conventionally a binder of ordinary" construction and in outline, the shocker attached thereto, the

details being omitted, this view being intendedonly to show the position of the shocker relative to the binder. Like characters of referenceindicate corresponding parts throughout the several views.

The improved shocker which forms the subject matter of this application comprises a frame supported upon traction wheels 10 and casters 11. The traction wheels are mounted rigidly upon the shafts12. from which the mechanism-receives motion, such shafts being rovided with spur gears 13 adjacent the traction wheels 10 intergeared with pinions 14 carried upon shafts 15 and with other gears 16 adjacent the middle of the structure intergeared with pinions 17 carried rigidly upon shafts 18. The shafts 15;

and 18 are vertical and adjacent the'forward end of the body and serve to transmit power to the severe} sprocket conveyer chains employed about' the structure. The superstructure comprises sides 19 and center partitions 20,.such center partitions being spaced apart Ward end. of the compartments adapted to l to form a chamber between the two comp'artments which are formed respectively by the said center artitions and the side walls 19.

At the orward end of the body and in front of the traction wheels 10 the side walls 19 converge as at 21 with a bottom 22 between such converging walls which is further reduced and twists to form the forward edge of the chute as shown at Figs. 1, 2, 4 and 8. The side walls 21 are also twisted, one forming the top of the chute shown at 23 and the other forming the bottom of the chute as shown at 24, such chute then being completed by the wall 22, top 23 and bottom 24 and adapted to be attached-at the delivery -end of a binder as shown particularly at Fig.3 andin position to receive sheaves in a horizontal position when delivered from such binder and by reason of the twist as illustrated, to change such sheaves from a horizontal to a vertical position as they are moveddown the chute, To insure the movement of the sheaves down the chute sprocket chains with fingers extending therefrom are mounted upon the chute and receive motion from the shafts 15. Such sprocket chains are employed in any desired number to accommodate the curvature of the chute and are shown as starting with chains 25 and 26 I upon the bottom of the chute. As these,

sprocket chains are driven in series from the shafts 15 they tend to convey the sheaves delivered from the binder through the chute upon the floor 22,- arriving in such latter position in standing or vertical position by reason of the twist of the chute.

Atthe forward ends of the walls 21 such Walls converge and a guide 33 is pivotally connected therewith as at 34 and provided with a spring 35 by which the said frame is held yieldingly with its point '36 against either of the converging walls 21. With the frame shown in the position seen at Fig. 1 a sheave passing from the chute will be guided by the guide into the compartment seen at the top of Fig. 1 and at the same time by engaging against the point 37 will reverse the guide so that the next sheave passing therethrough will passinto the compartment seen at the lower side of Fig.1 engaging against point 38 in passage and moving the guide back to the position shown in Fig. 1. By this arrangement, it will be seen that the sheaves are delivered alternately into the two compartments and are delivered into said compartments by the sprocket chains 25 and 26.

Alon-gthe outer sides of the compartments sprocket chains 39 and 40 are mounted to move, driven from sprockets carried upon the shafts 15. The rear ends of the sprocket chains 39 and 40 are carried upon shafts v which are journaled in frames 41 and 42 pivoted to swing upon the shafts 15 and held yieldingly with the fingers 43 extending within the compartments, such yielding engagement being provided by springs 44.

In the chamber between the center walls 20 sprocket chains 45 and 46 are also mounted to assist in moving the sheaves rearwardly, said sprocket chains also being pro vided with fingers 43 to engage the sheaves, such fingers 4,3 extending through the walls 20 into the compartments. It will therefore be seen that the sheaves passing down the chute will be turned to standing position and delivered alternately to the compartments and will be moved by the fingers 43 carried upon their respective sprocket chains rearwardly within such compartments.

To support the sheaves within the compartments a plurality of strips '47 extend longitudinally beneath the compartments and are provided with reduced portions 48 at their forward ends. The reduced portions 48 extend through the frame pieces 49 and 50 which form journal bearings per-.

mitting the said strips to rotate upon the reduced portion 48. The strips 47 are comparatively thin and flat so that when positioned in horizontal planes as'indica-ted at Figs. 1, 2 and 3 they serve to support the sheaves standing within the compartments and when turned to occupy vertical planes as indicated at Fig. 7 they permit the butts of the sheaves to engage the stubble or ground underneath such strips and to be. 105* prevent the sheaves from escaping from'the.

compartments. times when the contained sheaves are to be released a bail 55 is pivoted upon each of said doors and a link 56 extends from such bail upwardly to the latches 53. It is necessary then only .to raise the bails 55 whereupon the latches are raised out of engagement with the keepers 54 and the doors released. To accomplish such raising the bails 55 are provided with arms 57 through which extend rods 58 extending along the side of the machine and connected with crank arms carried upon a shaft 59. The shaft 59 is provided with a lever'GO by which the shaft To open the doors at the the rods 58 and the aoeaoca 59 is manipulated to draw the rcds"58 and unlatch the doors. lhe connection between armsis made by I meansof springs 61 so that the first'action raise the latch 53"by"llhe link 56, which is and 68. The shafts followed by the-swinging of the doors to open position". A collar 62 is provided rigidly upon the rods 58hby which a reverse movementgof the lever tends to close the doors. The shaft 59 is also provided with a s rocket 63 over which passes arsprocket cham 64 engaging sprockets 65 and co rigrespectivcly upon shafts 67 67 and 68 are journaled in the frame 69. which is'carried upon the shafts 12 and said shafts are respectively provided with crank arms and 73. The crank arms 70. and 71 are connected by links 72 and 73 respectively with-the ends of the frame pieces 49 and 50 which carry the strips 47, such ends being mounted to slide vertically, in the ides 74 andY-SJ It will be apparent, thererore, is manipulated to. open the doors 51, through the medium of the s'rocket'bhain 64 the shafts 67 and 68 will an be rotated to drop the strips d7, such stri .4 being" carried b the frame pieces 49 an 50 as above descri d.

To. accomplish the rotation of the strips 4:? to the position shown at Fig. 7 when the same are dropped the reduced portions 48 of such strips t? are each provided with a crank arm 76 which said crank arms are connected with strips 7'? so that as t e strips 77 are moved the'strips More moved to hori- ,ated at Figs.

zontal. or vertical planes as indie idly mounted 6 and 7. To accomplish such movement t' .e

adjacent ends of the strips 77 are connected to links 78 which in turn are pivotally con: nected with a block '79 connected by a spring to the frame 69; As the frame pieces 9 and 50 are dropped as above describe-(lithe block 79 is $11 ported practically against movement by t e spring 80 which through the medium of the links 79 serves to draw together the strips 77 and turn the strips 4:?

to vertical planes/as shown at Fig. '2' but that as the leverivotally when siiidi bottonri structure is raised by the return/{movement of the lever 60 the'said strips are also retro-nettle horizontal planes as indicated at Fig. 6,

To connect thedevice with the binder any apprpved con lingo are pnovided dependent 'u on the ma e o binder'td which the device! is attached, such binders ordinarily loci-rig provided with a bearing sleeve 81 to.

whif h the device is cbnnectcd by hookarms 82 and by such further connecting means, as may he muenecessa as for instance the bar 83.- lltis tube on erstcod' that the corn frame, a housing comprising necting means is degendent upon "the structure to which the s oclier is attached and may be varied at'will."

' 'io retain the frame and walls their proper position arched members 84 at the front an 85 at the rear are provided.

rigidly in 1 i When the shock'is being formed, a set of j fingers 86 carrie'd'upon a rod 87 is thrown into the compartments to prevent the ea c of any newly formed sheaves on to the strips'l'l until the latter have been raised to loading positions. The rods extend through the walls 19 upon which they are pivoted, and are connected to rod 58, so that as the latter swings to open the doors'51, the fingers 86 are thrown into place, as shown in' n operation, therefore, the'device is attached to the hinder in the manner described, asfor instance as shown at Fig. 8, sheaves are delivered to the chute and are turned to vertical position and alternately pas- L guided to the two compartments"and are moved by the sprocket chains to the rear of such compartments or as near the rear of the compartment as compartments will permit. W hen the compartments have been sufieiently filled to consi-itute a shock the lever to drop the supportinguncmbers 47 and open the end doors which permits the standing sheaves to engage the stubble oround an the filled condition of such- 0 is manipulated at the same time to be moved by the eging side sprocket lar course of cutting and binding the grain.

I claim: 1. In a checker, a wheel-so ported main out and side I frame; a movable auxiliary frame mounted on a rocker shaft carried by the housing, and arranged to be raised to, and lowered fromthe housing; slats pivotally mounted in the auxiliary frame and forming a bottom for the housing; crank arms carried by each of the slats; strips connecting the outer ends of said crank arms; links connecting the ends of the strips, and having their inner ends attached to a block connected to the main frame,
